M74LCX16244DTR2G集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書(shū)PDF中文資料

M74LCX16244DTR2G屬于集成電路（IC）的緩沖器驅(qū)動(dòng)器接收器收發(fā)器。由安森美半導(dǎo)體公司制造生產(chǎn)的M74LCX16244DTR2G緩沖器，驅(qū)動(dòng)器，接收器，收發(fā)器邏輯緩沖器、驅(qū)動(dòng)器、接收器和收發(fā)器允許隔離對(duì)某個(gè)電路的邏輯信號(hào)的訪(fǎng)問(wèn)，以用于另一電路。緩沖器將其輸入信號(hào)（不變或反相）傳遞到其輸出，并可能用于清除弱信號(hào)或驅(qū)動(dòng)負(fù)載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線(xiàn)之間進(jìn)行隔離通信。

The MC74LCX16244 is a high performance, non?inverting 16?bit

buffer operating from a 2.3 to 3.6 V supply. The device is nibble

controlled. Each nibble has separate Output Enable inputs which can

be tied together for full 16?bit operation. High impedance TTL

compatible inputs significantly reduce current loading to input drivers

while TTL compatible outputs offer improved switching noise

performance. A VI specification of 5.5 V allows MC74LCX16244

inputs to be safely driven from 5.0 V devices. The MC74LCX16244 is

suitable for memory address driving and all TTL level bus oriented

transceiver applications.

The 4.5 ns maximum propagation delays support high performance

applications. Current drive capability is 24 mA at the outputs. The

Output Enable (OEn) inputs, when HIGH, disable the outputs by

placing them in a HIGH Z condition.

The MC74LCX16244 contains sixteen non?inverting buffers with

3?state 5.0 V?tolerant outputs. The device is nibble controlled with

each nibble functioning identically, but independently. The control

pins may be tied together to obtain full 16?bit operation. The 3?state

outputs are controlled by an Output Enable (OEn) input for each

nibble. When OEn is LOW, the outputs are on. When OEn is HIGH,

the outputs are in the high impedance state.
